Interplay between disorder and inversion symmetry: Extreme enhancement of the mobility near the Weyl point in BiTeI

open access: yes, 2015
We show experimental and theoretical evidence that BiTeI hosts a novel disordered metallic state named diffusive helical Fermi liquid (DHFL), characterized by a pair of concentric spin-chiral Fermi surfaces with negligible inter-valley scattering.

Study on utility optimization for randomized response mechanism

open access: yesTongxin xuebao, 2019
For the study of privacy-utility trade-off in local differential privacy,the utility optimization models of binary generalized random response mechanism for the case of differential privacy and approximate differential privacy were established.By graphic

Experimental investigation of an interior search method within a simple framework [PDF]

open access: yes, 1986
A steepest gradient method for solving Linear Programming (LP) problems, followed by a procedure for purifying a non-basic solution to an improved extreme point solution have been embedded within an otherwise simplex based optimiser.

On the black hole limit of electrically counterpoised dust configurations

open access: yes, 2011
By means of a simple scaling transformation any asymptotically flat Papapetrou-Majumdar solution of the Einstein-Maxwell equations corresponding to a localized regular distribution of electrically counterpoised dust can be reformulated as a one-parameter

On the extreme points of moments sets [PDF]

open access: yesMathematical Methods of Operations Research, 2016
Necessary and sufficient conditions for a measure to be an extreme point of the set of measures (on an abstract measurable space) with prescribed generalized moments are given, as well as an application to extremal problems over such moment sets; these conditions are expressed in terms of atomic partitions of the measurable space. It is also shown that

Possible impact of urbanization on extreme precipitation–temperature relationship in East Asian megacities

open access: yesWeather and Climate Extremes, 2021
This study investigates the possible impact of urbanization on the summertime extreme precipitation–temperature (P–T) relationship in East Asia. The local climate in three megacity regions—Guangdong in China, Seoul/Gyeonggi in Korea, and Tokyo in Japan ...

Extreme Points and Rotundity in Musielak-Orlicz-Bochner Function Spaces Endowed with Orlicz Norm

open access: yesAbstract and Applied Analysis, 2010
The criteria for extreme point and rotundity of Musielak-Orlicz-Bochner function spaces equipped with Orlicz norm are given. Although criteria for extreme point of Musielak-Orlicz function spaces equipped with the Orlicz norm were known, we can easily ...

Extremal multipliers of the Drury-Arveson space [PDF]

open access: yesarXiv, 2016
We give a new characterization of the so-called quasi-extreme multipliers of the Drury-Arveson space $H^2_d$, and show that every quasi-extreme multiplier is an extreme point of the unit ball of the multiplier algebra of $H^2_d$.

Ergodicity and extremality of AMS sources and channels

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2003
Asymptotically mean stationary (AMS) sources (probability measures) and channels are considered as an extension of stationary sources and channels. It is shown that each extreme point of the set of all AMS sources is ergodic, but not vice versa, and that
